An intensive behavioral weight loss intervention and hot flushes in women.

ABSTRACT: Higher body mass index is associated with worse hot flushes during menopause but the effect of weight loss on flushing is unclear.Self-administered questionnaires were used to assess bothersome hot flushes in a 6-month randomized controlled trial of an intensive behavioral weight loss program (intervention) vs a structured health education program (control) in 338 women who were overweight or obese and had urinary incontinence. Weight, body mass index, abdominal circumference, physical activity, calorie intake, blood pressure, and physical and mental functioning were assessed at baseline and at 6 months. Repeated-measures proportional odds models examined intervention effects on bothersome hot flushes and potential mediating factors.Approximately half of participants (n = 154) were at least slightly bothered by hot flushes at baseline. Among these women, the intervention was associated with greater improvement in bothersome flushes vs control (odds ratio [OR] for improvement by 1 Likert category, 2.25; 95% confidence interval [CI], 1.20-4.21). Reductions in weight (OR, 1.32; 95% CI, 1.08-1.61; per 5-kg decrease), body mass index (1.17; 1.05-1.30; per 1-point decrease), and abdominal circumference (1.32; 1.07-1.64; per 5-cm decrease) were each associated with improvement in flushing, but changes in physical activity, calorie intake, blood pressure, and physical and mental functioning were not related. The effect of the intervention on flushing was modestly diminished after adjustment for multiple potential mediators (OR, 1.92; 95% CI, 0.95-3.89).Among women who were overweight or obese and had bothersome hot flushes, an intensive behavioral weight loss intervention resulted in improvement in flushing relative to control.

Project description:BACKGROUND:Efforts to translate evidence-based weight loss interventions, such as the Diabetes Prevention Program (DPP), to low-income postpartum women have resulted in poor intervention attendance and high attrition. Strategies that improve engagement and retention in this population are needed to maximize the reach of evidence-based weight loss interventions. OBJECTIVE:The objective of this study was to adapt a DPP-based weight loss intervention (Fresh Start) for Facebook delivery and to evaluate its feasibility among low-income postpartum women. METHODS:This study comprised 3 single-group pilot studies where feasibility outcomes iteratively informed changes from one pilot to the next. We paralleled the in-person program for Facebook delivery by translating the protocol to a content library of Facebook posts with additional posts from lifestyle coaches. Low-income postpartum women were recruited from Women, Infants, and Children (WIC) clinics in Worcester, Massachusetts. Participants were enrolled into a 16-week weight loss intervention delivered via Facebook. During the first 8 weeks, Facebook intervention posts were delivered 2 times per day, with additional posts from coaches aiming to stimulate interaction among participants or respond to participants' questions and challenges. For the following 8 weeks, posts were delivered once per day without additional coaching. Feasibility outcomes were engagement (defined by number of likes, comments, and posts measured throughout intervention delivery), acceptability, and retention (survey at follow-up and assessment completion rate, respectively). Changes in weight were also assessed at baseline and follow-up. RESULTS:Pilot 1 had a retention rate of 89% (24/27), and on average, 62% (17/27) of women actively engaged with the group each week during the 8-week coached phase. Mean weight loss was 2.6 (SD 8.64) pounds, and 79% (19/27) would recommend the program to a friend. Pilot 2 had a retention rate of 83% (20/24), and on average, 55% (13/24) of women actively engaged with the group weekly during the 8-week coached phase. Mean weight loss was 2.5 (SD 9.23) pounds, and 80% (16/24) would recommend the program to a friend. Pilot 3 had a retention rate of 88% (14/16), and on average, 67% (11/16) of women actively engaged with the group weekly during the 8-week coached phase. Mean weight loss was 7.0 (SD 11.6) pounds, and 100% (16/16) would recommend the program to a friend. CONCLUSIONS:Our findings demonstrated that a Facebook-delivered intervention was acceptable and could be feasibly delivered to low-income postpartum women. Future research is needed to evaluate the efficacy of a Facebook-delivered weight loss intervention.

Project description:ObjectiveVasomotor flushing (hot flushes) is a common menopausal symptom experienced by most women going through the menopausal transition; flushing continues for a variable period in postmenopause. Primarily due to lack of ovarian estrogen, other biomarkers of hot flushes have not been clearly identified. We examined the relationship of hot flushes with ghrelin and adipokines.MethodsBaseline data from two clinical trials, the Women's Isoflavone Soy Health (WISH) trial and Early versus Late Intervention Trial of Estrogen (ELITE), were used in this post hoc cross-sectional study. Both WISH and ELITE had similar study designs, inclusion criteria, and data collection processes. Study participants were healthy postmenopausal women not taking estrogen-based hormone therapy, free of cardiovascular disease, or any other chronic diseases. Both trials used the same hot flush diary in which participants recorded the number of daily hot flushes by severity over a month on average. Serum concentrations of ghrelin, leptin, adiponectin, and resistin were assessed in stored fasting blood samples using highly specific radioimmunoassay. In this analysis, self-reported flushing experience was tested for an association with leptin, adiponectin, resistin, and ghrelin concentrations using logistic regression and mean comparisons.ResultsA total of 898 postmenopausal women from the ELITE and WISH trials contributed to this analysis. Mean (SD) age was 60.4 (7.0) years, body mass index (BMI) 27 (5.3) kg/m, 67% were white, and 47% were within 10 years of menopause. Reported flushing was significantly associated with younger age, lower education, lower BMI, being married, and more recent menopause. Adjusted for these factors other than BMI, women in the highest quartile of ghrelin had significantly greater likelihood of experiencing hot flushes (OR [95% CI] = 1.84 [1.21-2.85]) compared to women in the lowest quartile. The association was more pronounced among overweight or obese women (OR [95% CI] = 2.36 [1.28-4.35]) compared to those with normal BMI (1.24 [0.54, 2.86]; interaction P value = 0.46). The association between ghrelin and hot flushes was similar among early (within 10 y) and late (over 10 y) postmenopausal women. Blood levels of adiponectin and resistin were not associated with hot flushes.ConclusionsHigher concentrations of ghrelin were associated with greater likelihood of hot flushes in both early- and late-postmenopausal women. Leptin, adiponectin, and resistin levels were not associated with hot flushes in postmenopausal women.
